LARS W. BODINSON, OF AURORA, ILLINOIS, ASSIGNOR TO THE AMERICAN WELL WORKS,

OF AURORA, ILLINOIS, A CORPORATION OF ILLINOIS.

DEEP-WELL PUMP.

Specification of Letters Patent.

Patented Dec. 31, 1918.

To all whom it may concern:

Be it known that I, LARS W. BODINSON, a citizen of the United States, residing at Aurora, in the county of Kane, State of Illinois, have invented certain new and useful Improvements in Deep-VV'ell Pumps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to deep well pumps of the plunger type, and it has for its principal object the provision of a new and improved form and arrangement of parts in a single-acting pump of this type whereby an increased amount of water can be pumped. As will be readily appreciated, in the use of a double-acting plunger pump, in the application of power to the pump rod for the down stroke of the plunger the rod has a tendency to buckle so as to be brought into contact with adjacent parts between its bearings, causing abnormal wearing of the parts. In wells in some formations through which it has been found impossible to drill perfectly straight, the wear caused by the buckling of the pump rods is so great as to make the use of double-acting pumps undesirable.

It is another object of my invention to provide a construction in an improved pump of the type described by reason of which the pump rods and the plungers operated thereby may be drawn upward out of operative position whenever desired for replacing or repairing the plungers. It is another object of my invention to provide such a construction in which one or more of the cylinders in which the plunge-rs operate may be raised to the surface with the plungers by means of thepump rods without the removal of the pump casings. It is another object of my invention to provide improvements in the system of pump rods used for operating the plungers, involving improved bearing means and suitable means for lubricating such bearings. It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out.

The preferred means by which I have accomplished my objects are illustrated in the accompanying drawings and are hereinafter specifically described. That which I believe to be new and desire to claim by this application is set forth in the claims.

In the drawings, the figures are sectional views, being broken away at many points for varying distances in order to illustrate the construction fully without unduly eX- tending the views.

Figure 1 is a view showing the upper part of the pump and the means for connecting the pump rods to the actuating mechan1sm;

Fig. 2 is a view of the upper part ofthe pumping mechanism located at the bottom of the well;

Fig. 3 is a continuation downward from the part shown in Fig. 2, and Fig. 4: is a con tinuation downward from the parts shown in Fig. 3;

Figs. 5 to 12, inclusive, are horizontal cross-sections taken upon the correspondingly-numbered section lines of Figs. 2, 3 and 4:; i

Fig. 13 is a view showing one form of the devices by which the pump rods are connected together, and are spaced'relative to each other;

Fig. 14 is a cross-section taken on line 14-14: of Fig. 15, Fig. 15 being a central vertical section showing a modified form of connections for the sections of pump rod;

Fig. 16 is a view showing still another form of coupling devicesfor connecting the different sections of pump rod;

Fig. 17 is a view of the upper portion of a modified form of pumping apparatus located in thebottom of a well, and Figs. 18, 19 and 20 show successively lower portions of such pumping apparatus;

Fig. 21 shows another modified form of the upper portion of the pumping apparatus located at the bottom of the well, and Figs. 22 and 23 show successively lower portions of such pumping apparatus Fig. 24 shows still another modified form of the upper portion of the pumping apparatus located at the bottom of the well, and Figs. 25 and 26 show successively lower portions of such pumping apparatus Referring to Figs. 1 to 13, inclusive, in which corresponding parts are indicated by the same reference characters, 30 indicates a T-connection mounted by means of screwthreads upon the upper end of a well-pipe 31 extending downward into the well 32. Connected by means of screw-threads to the T-connection 30 is a water-delivery pipe 33 by which the water is adaptedto be led to any'suitable point. As is clearly shown in Fig. 1, the upper end of the connection 30 is closed by a plate 34 through which a tubular pump rod 35 extends, a stuffingboX 36 of any suitable type being interposed between the pump rod 35 and the plate 34. A cross-head 37 is mounted by means of screw-threads upon the upper end of the pump rod 35, being locked in position thereon by means of a jam-nut 38. A cap 39 closes the upper end of the pump rod 35 about a second pump rod 40 extending downward into the tubular pump rod 35, suitable packing 41 being held about the pump rod 40 in a suitable recess in the cap 39 adjustably closed at its upper end by a suitable gland 42. The upper end of the pump rod 40 has a cross-head 43 connected to it by'means of screw-threads, the crosshead being locked in position by means of jam-nuts 44. Communicating with the interior of the pump rod 35 near its upper end is a pipe ortube 45, in the construction shown a valve 46 of any suitable type being interposed for controlling the flow from the pipe 45 to the tubular pump rod The cross-heads 37 and 43 are designed to be reciprocated vertically by any suitable mech anism, not shown. It will be understood that these cross-heads may be reciprocated always in opposite directions whereby one of the pump rods reaches its highest point when the other pump rod reaches its lowermost position, the pump rods being adapted to travel always in opposite directions. I prefer, however, to have the cross-heads reciprocated vertically by a driving means such as that shown and claimed by Letters Patent of the United States, No. 1,124,295, issued on January 12, 1915, to The American Well Works as the assignee of Matthew T. Chapman, by the use of which construction the upward stroke of each pump rod is caused to begin before the other pump rod reaches its uppermost position.

Referring particularly to Fig. 13, which shows one form of pump rods designed to be used, it will be seen that the pump rod 40 is composed of sections joined together by means of screw-threaded couplings 47 and that the pump rod 35 is likewise formed of sections joined together by screw-threaded couplings 48. At the lower end of each section ofthe pump rod 35 a block 49 of wood, or of any other suitable material, is secured in any suitable manner, said block preferably having a close fit in the section 35, but having a suitable working lit about the pipe 40. By the use of a plurality of such blocks 49 throughout the line of pump rod sections 3540, the inner pump rod is spaced away from the tubular pump rod so as to avoid undue wear between said rods.

The pipe 45 adapted to be connected at its outer end wlth any suitable source of l11brl cant, water, 011, grease or any other suitable lubricant being adapted to be used for this purpose. It will be understood that in cases where the pump is being used for raising water for domestic purposes, it is preferred that pure filtered water be used for lubricating purposes in order not to impair the potability of the water.

Referring now to Figs. 2, 3 and 4, it will be seen that the pumping apparatus at the bottom of the well comprises a cylinder 50 secured by means of a coupling 51 to the lower end of the well pipe 31, a cylinder 52 of-smaller diameter than the cylinder 50 secured to the lower end of said cylinder 50 by means of a coupling 53, pistons or plunadapted to be reciprocated in unison by the pump rod 35.

Coming now to a more detailed descrip tion of the pumping apparatus at the bottom of the well, 58 indicates a sleeve (see Figs. 2 and 5) secured by means of screwthreads to the lower end of the pump rod 35. The sleeve 58 is connected by, means of webs 59 with a sleeve 60 having a sliding fit in the well pipe 31 serving thus to hold the pump rods centered relative to the well pipe. Formed integrally with the sleeve 58 in the construction shown is a head 61 which has a working fit upon the pump rod 40. Secured by means of screw-threads upon the lower end of the pump rod 40 below the head 61 is a thimble 62, in the lower end of which is secured by means ,of screw-threads a spider 63 (see Fig; 6) comprising a plurality of arms 64, a sleeve 65, and radially-extending webs 66 engaging at their outer ends the inner surface of the well pipe 31. Secured to the sleeve by means of screwthreads and extending downwardly there from, is a cylindrical pump rod section 67. Secured by means of screw-threads tothe spider 63 at its central point is another pump rod section 68, both of such sections 67 and 68 being adapted to be reciprocated in unison by the pump rod 40, as will be readily understood. A jam-nut 69 is mounted on the upper end of the pump rod section 68 for further securing such section in position. Slidably mounted upon the pump rod section 68 within the cylindrical pump rod section 67 is a head 70 (see Fig. 7). The head has connected to it by means of webs 71 a coupling 72, to the lower end of which there is connected by means of screw-threads a tubular pump rod section 73, water being adapted to pass through the coupling 72 about the pump rod section 68 between the webs 71. The heads 61 and 70 are rigidly connected to each other by a plurality of links 74 which pass through suitable verti cally-extending openings through the said heads, nuts 75 being provided on the ends of said links for holding the heads firmly in contact with suitable shoulders on the links. As will be seen from the above description, the pump rod section 73 is virtuallyan eX- tension of the pump rod 35, being adapted to be actuated in unison therewith, the break in the tubular pump rod between the heads 61 and 70 being necessary in order to permit the connection of the pump rod 40 with the pump rod section 67' surrounding the pump rod section 73.

The plunger 54 comprises an annular outer portion 76 joined by radially-extend ing webs 77 to an inner sleeve portion 78 which is joined at its upper end by means of a coupling 79 to the lower end of the cylindrical pump rod 67. Extending upward about the tubular pump rod section 73 inside of the cylindrical pump rod section 67 is an annular flange 80, which, in the construction shown, is formed integrally with the coupling member 79, such flange being provided for the reception of packing 81 of any-suitable type held adj ustably in position therein by means of a gland 82 secured by means of screw-threads upon the upper end of the flange 80. Suitable packing rings 83 are mounted upon the outer face of the annular outer portion 76 of the plunger 54, being held adj ustably in position thereon by suitable nuts 84. The upper end of the annular passage through the plunger 54 between the webs 77 is adapted to be closed by a valve 85 which is slidably mounted upon the sleeve portion 7 8' of the plunger so as to be adapted to rise freely thereon, being limited in its upward movement by contact with the coupling member 79.

The plunger comprises a sleeve 86 by which the lower end of the tubular pump rod section 73 is joined to the upper end of a tubular pump rod section 87, said sleeve portion 86 being joined by means of webs 88 with an annular outer portion89 having a working fit in the cylinder 50, suitable packing 90 being interposed between said'two parts. A valve 91 is slidably mounted upon the sleeve-portion 86 adapted to close the annular passage between the webs 88 the valve 91 being limited in its upward movement by a cap 92 mounted by means of screwthreads on the upper end of the sleeve 86.

The coupling member 53 comprises two tapering sleeves 93 'and94 joined by webs 95,

in the construction shown the said parts being formed integrally with each other. As is shown in Fig. 3 the cylinder 52 is made of slightly smaller diameter than the. cylinder 50 in order to accommodate the taper off' the sleeves 9394 to provide a tapering seat for the valve-cage 96 (see Figs.

3 and 9). This valve-cage 96 comprises a bell-shaped sleeve portion 97 slidably mounted upon the pump rod section 87 and having suitable packing 98 interposed between its inner face and the pump rod section 87, such packing being held adjustably in position by a cap sleeve 99. An annular outer portion 100 is secured to the bell-like portion 97 by means of webs 101, in the construction shown said three portions being formed integrally with each other. The outer face of the annular portion 100and the outer face of the lower portion of the bell-like Sleeve 97 are shaped to conform to the tapering portions 93 and 94 of the coupling 53, respectively, suitable packing 102-103, respectively, being provided. A valve 104 is slidably mounted upon the upper end of the sleeve 97, being limited in its upward movement thereon by a sleeve 105 secured by means of screw-threads on the upper end of said sleeve, the valve 104 being adapted to close the annular passage-way between the webs 101. As will be appreciated from an inspection of Fig. 3, the cage 96 and the coupling 53 provide a free passage-way between the interior of the cylinder 50 and the exterior thereof, except as such passage-way is closed by the valve 104; the cylinders 50 and 52 are properly secured together; and the cage 96 carrying with it the valv 104 is adapted to be lifted readily out of position in the coupling member 53. By reason of the taper of the parts the cage 96 is adapted to assume proper position relative to the coupling 53 upon the cage 96 being let down therein.

As is best shown in Figs. 4 and 10, 106 indicates a coupling comprising a sleeve 107 connected by means ofscrew-threads to the lower nd of the tubular pump rod section 87 and a sleeve 108 connected as hereinafter described to the plunger 56. The sleeves 107 and 108 are connected together by means of webs 109 whereby the lower end of the tubular pump rod 87 opens into the cylinder 52. The piston or plunger 56 comprises a sleeve 110 joined by webs 111- to an annular outer portion 112. The upper nd of the sleeve 110 is joined by means of screw-threads to the sleeve 108, suitable packing 113 being provided between the sleeve 110 and the The plunger 57 comprises a sleeve 117 mounted by means of screw-threads upon the lower end of'the pump rod section 68, as shown in Fig. 4 a jam-nut 118 being employed for locking the said sleeve in position thereon. The sleeve 117 is connected by means of radially-extending webs 118 with an annular outer portion 119, the sleeve 117, the webs 118 and the annular portion 119 of the plunger being preferablyv formed integrally with each other. The plunger 1191s provided with suitable packing 120 on its outer face engaging the inner face of the cylinder 52. A valve 121 is slidably mounted upon the upper end of the sleeve 117, being limited in its upward movement there on by a nut 122 secured by means of screwthreads upon the upper end of said sleeve. The valve 121 is adapted to close the annular passage-way between the sleeve 117 and the.

annular portion 119 of the piston or plunger 57, as will be readily understood.

A sleeve 123 is mounted by means of screw-threads upon the lower end of the cylinder 52, providing a tapering seat for the annular outer portion 124 of a valve-cage, such annular portion 124 being adapted to fit closely against its seat. Webs 125 serve to connect the annular portion 124 of the valve-cage with a sleeve portion 126, the sleeve 126, webs 125 and annular portion 124 being preferably formed integrally with each other. A valve 127 is slidably mounted upon the sleeve 126, being limited in its up ward movement thereon by a sleeve 128 mounted by means of screw-threads upon the upper end of said sleeve. The valve 127 is adapted to close the passage-way between the webs 125 of the valve-cage, serving thus to close the lower end of the cylinder 52.

Radially-extending flanges 129 are formed with the sleeve 123 serving to center said sleeve in the well 32. As will be readily understood, the said valve-cage is adapted to be lifted out of engagement with'the sleeve 123, and is adapted to resume tight gripping engagement with said sleeve upon being again lowered through the cylinder 52.

With the cross-heads 43 and 37 being reciprocated by any suitable means,for eX- ample, by a device of the type shown in Patent No. 1,124,295, above referred to, the pistons or plungers 54 and 55 will be reciprocated in opposite directions in the cylinder 50, and the pistons or plungers 56 and 57 will be reciprocated in opposite directions in the cylinder 52. As before explained, in such operation the upward stroke of either piston in either one of the cylinders be ins before the end of the upward stroke of the other piston in the same cylinder, but generally speaking the plungers may be said to be operated in opposite directions.

WVith the pistons 56 and 57 being oper- 'ated in opposite directions in the cylinder 52 as just described, when the piston 56 is moved upward in the said cylinder the valve 115 serves to close the upper end of the said piston causing the water to rise past the valves 121 and 127 which are lo cated in the said cylinder below the piston 56. In this upward movement of the piston 56 the water, in the upper end of the cylinder 52' is forced upward through the pump.

rod section 87, through the pump rod section 73, into the cylindrical pump rodv section 67 and thence upward through the well pipe 31 to. the surface. Just before the plunger 56 reaches its uppermost position, the plunger 57 will have started upward, drawing water past the valve 127 to fill the lower end of the cylinder 52. Upon the While the piston '56 is being forced upward in the cylinder 52 the piston 55 is also being forced upward in the cylinder 50, filling the lower end of the cylinder 50 with water rising past the valve 104. Shortly after the start of-the upward stroke of the piston or plunger 55, the piston 54 is started on its downward stroke, and the water in the cylinder 50 between the plungers 54 and 55 is consequently forced upward past the valve in the plunger 54, a portion of such water serving to fill the upper end of the cylinder 50' above the descending piston 54 and the remainder thereof being caused to rise through the well pipe 31. Upon the reversal of direction of movement of the piston 54 the water in the cylinder 50 above the piston 54 is forced upward through the well pipe 31, water being forced upward past the valves 104 and 91 for filling the cylinder 50 between the plungers '54 and 55.

With the pump rods 40 and 35 beingreciprocated by such a device as that shown in the Chapman Patent, 1,124,295, above referred to, the column of water rising through the well pipe 31 will be kept in continuous upward movement, thus avoiding the necessity for overcoming the inertia of the water where it is permitted to stop between successive strokes of the various plungers. All of the operation of raising the water is effected by the upward movement of the pump rod parts, in which upward movement of the pump rods the tendency is to cause the pump rods to straighten their alinement relative to each other and relative to. the well pipe rather than to buckle as is the case in a double-acting pump. By reason of the construction of the parts, the pump rods are free to be withdrawn readily carrying upward with them the entire system of valves and plungers with the exception of the valve 127 the cage 96 with its valve 104 being adapted to be raised with the pump rod by reason of the coupling 106 beingbrought into contact with the cap or gland 99, serving to lift the cage as a whole from its seat. The valve 127 is adapted to be withdrawn if desired by the use of any suitable mechanism, such valve being adapted to be lifted freely from its seat in the sleeve 123. By the use of the bearing-blocks 49 in the tubular pump rod sections 35, the pump rods are held in proper alinement relative to each other so as to avoid any undue friction or wear upon such parts. By the expedient of forcing pure water orother suitable lubricant down the tubular pump rod 35 the bearings between the pump rod 40and the blocks 49 are kept .in good working condition. If desired the water for lubricating purposes can be forced downward through the tubular pump .rod 35 so as to wash out from the bearings any grit or sand which might be lodged therein, such supply of water under pressure serving also to wash out any grit or sand which might work its way between the head 61 and the lower end of the pump rod 40. Indeed this result would be accomplished under normal conditions whether or not the water were supplied to the tubular pump rod 35 under pressure, the head of the water in such pump rod above the part 61 being sufficient for maintaining the bearing of the part 61 upon the pump rod 40 in proper condition. While I have shown no means of communication between the interior of the tubular pump rod 35 at its lower end and the well pipe 31 about the pump rod 35 except through the working bearing of the head 61 upon the pump rod 40, it will be understood that I do not wish to restrict ,myself to this particular construction except as hereinafter specifically claimed, inasmuch as any suitable expedient may be adopted for making such communication more ample if the communication through the bearing of the head 61 is found to be insufiicient.

In Figs. 14 and 15 in which a slightly modified form of coupling'devices is shown, I have indicated corresponding parts by the same reference characters as in Figs. 1 to 13, but with the addition of the exponent a. In the construction there shown a coupling sleeve 130 is used in lieu of the sleeve 48 shown in Fig. 13, such sleeve 130 being joined by mean of webs 131 to an outer sleeve member 132 adapted to have a sliding fit in the well pipe 31*. A block '133 of wood or other suitable material is mounted in the sleeve 130 between the sections of the tubular pump rod 35*, such block 133 having a working fit upon the pump rod 40, serving as a bearing therefor.

In Fig.16, which shOWs still another form of coupling device, I have indicated corre- .sponding parts by the same reference characters, but with the addition of an exponent b. In thi construction a. sleeve 134, having fixed therein a block of wood or other suitable material 135, is used for connecting the sections of the pump rod 35". A coupling 136 having a tapering threaded opening for the reception of the ends of the sections of the pump rod 40 is used for connecting said sections in lieu of the coupling sleeve 47 shown in Fig. 13.

In Figs. 17, 18, 19 and 20, which show a modified form of pumping-apparatus at the bottom of the well, I have indicated corresponding parts by the same reference numerals as are used in Figs. 1 to 13, but with the addition of an exponent c. In the construction shown in said figures, the lower end of the cylinder 50 and the upper endof the cylinder 52 are joined together by a modified form of coupling device by which a valve at this point is dispensed with. In this construction, 137 indicates a sleeve secured by means of SCI'8WthIGELCig upon the lower end of the cylinder 50, and 138 indicates a second sleeve formed integrally with the sleeve 137, joined by means of webs 139 to a third sleeve 140 which is connected by means of screw-threads to the upper end of the cylinder 52. The upper portion of the sleeve 140 and the inner face of the sleeve 138 provide tapering seats in alinement with .each other for a member 141 serving to close the upper end of the cylinder 52 and to afford a uitable outlet from the lower end of the cylinder 50. The member 141 is provided with suitable packing 142 at its lower end in engagement with the inner face of the tapering sleeve .140 and is provided with suitable packing 142 between its lower end and the tubular pump rod section 87. The said closure member 141 comprises also radially-extending webs 144 connected at their outer edges to a sleeve 145 .having suitable packing 146 in engagement with the tapering seat provided by the sleeve 138. The construction is such that the member 141 and theparts connected therewith serve'to close tightly the upper end of the cylinder 52 and provide an annular passage cooperating with the annular passage between the sleeves 138 and 140 for providing a suitable port from the lower end of the cylinder 50 The said closure member 141 is adapted to be lifted readily out of position by means of the coupling 106upon the withdrawal of the pump rods;

147 indicates a .well tube section secured by mean of screw-threadsuponthe sleeve 138 and extending downward therefrom about the cylinder 52.

the cylinder 52, as shown in Fig. 4, the sleeve 148 providing a taperlng seat for the annular outer member 124 which supports the valve 127. The sleeve 148 is provided with radially-extemling flange or ribs 149 and has secured to its lower end by means of screw-threads the upper end of a downwardly-extending pipe 150.

By the provision of the pipe or tube 147 about the cylinder 52 leading downward from the cylinder 50 the necessity for placing the lower end of the cylinder 50 below the level at which thewater is adapted to stand in the well is avoided. The valve 127 is also adapted to perform the function of the two valves 127 and 104 of the construction first described.

In Figs. 21, 22, and 23, which show a modified form of structure, the parts corresponding to the parts shown in Figs. 1 to 13 are indicated by the same reference characters, but with the addition of an exponent d. In this construction a cylinder 151 of the same size as the cylinder 50 is provided in lieu of the cylinder 52 of Figs. 1 to 13, the cylinder 151 being joined at its upper end to the cylinder 50 by a coupling comprising a bell-shaped leeve 152 and a sleeve 153 joined to the sleeve 152 by means of webs 154. The valve 104 is slidably mounted upon the upper end of the sleeve 152 so as to be adapted to close the annular opening between the sleeves 152 and 153, being limited in its upward movement thereon by a collar 155 secured by means of screw-threads above the valve 104. Suitable packing 156 is held in position between the sleeve 152 and the tubular pump rod section 87 by means of an adjustable gland 157. In the construction shown in said Figs. 21,22 and 23, the pump rods together with the pistons and valves are incapable of being removed except upon the removal of the well pipe 31 and the cylinders 50 and 151.

In Figs. 24, 25 and 26, the parts which correspond to the structure shown in Figs. 1 to 13 are indicated by the same reference characters, but with the addition of an exponent e. In this construction, the well pipe is indicated by the numeral 158 and is continued downward past the upper end of the upper cylinder which is indicated by the numeral 159. A sleeve 160 is mounted by means of screw-threads upon the upper end of the cylinder 159 serving to hold the cylinder centered relative to the well pipe 158. The lower end of the well pipe 158 is, joined to the upper end of the lower cylinder 52 by means of a coupling comprising two sleeves 161 and 162 joined by webs 163. In this con- 'struction' the lower end of the upper cylinder 159 is adapted to be closed by a valve 164 slidingly mounted upon the upper end of a sleeve 165 which is joined by means of webs 166 to an outer sleeve member 167, the said valve 164 being limited in its upward opening movement by a sleeve 168 mounted by means of screw-threads upon the upper end of the sleeve 165. Suitable packing 169 is interposed between the sleeve 165 and the tubular pump rod section 87, said packing being held in position by an adjustable gland 170. By this construction the upper cylinder 159 is adapted to be withdrawn from the well together with the pump rods, pistons and valves, being free to be lifted out of the tapering seat provided by the sleeves 161 and 162, the valve-cage at the bottom of the cylinder being adapted to seat itself, upon the re-insertion of the mechanism in the well tube, in proper position relative to the annular passage between the sleeves 161 and 162.

lVhile I have shown valve mechanism in connection with each form of structure illustrated adapted to act independently of thevalves in the plungers for preventing the downward movement of the water, it will be understood from a study of the operation of the device that such stationary valve mechanism is not essential to the operation of the pump, and I do not wish to restrict myself to the use of such stationary valve mechanism except as hereinafter specifically claimed. Indeed, it is probable that, during the normal operation of the pump, when driven by such a device as that shown by the Chapman Patent, 1,124,295, above referred to, the valves 104 and 127 of the construction of Figs. 1 to 13 and the corresponding valves of the other constructions would not close at all inasmuch as there is a continuous upward flow of water through each of the cylinders.

These valves serve, however, to relieve the strain upon the piston valves when the pump is not in operation and the employment of such valves is therefore to be desired.

While I have described the parts 50 and 52 of Figs. 1 to 13 and the corresponding parts of the other figures as cylinders, it will be understood that such parts might equally well be termed well pipe sections or well tube sections serving as cylinders, with the possible exception of the cylinder 159 which is removable relative to the well pipe. It will be understood that I do not wish to be restricted to the use of separate cylinders in lieu of extensions of the well pipe of proper size and description except as the claims may specifically designate the cylinders as being formed separately or as being removable from the well pipe, the word cylinder being used broadly in the specification and claims to indicate the tube or portion of a tube or other receptacle within which the plungers are operated for raising the t r,
